Tell Ruby Program to Wait some amount of time

How do you tell a Ruby program to wait an arbitrary amount of time before moving on to the next line of code?

Solution

  • Like this:

    sleep(num_secs)

    The num_secs value can be an integer or float.

    Also, if you're writing this within a Rails app, or have included the ActiveSupport library in your project, you can construct longer intervals using the following convenience syntax:

    sleep(4.minutes)
# or, even longer...
sleep(2.hours); sleep(3.days) # etc., etc.
# or shorter
sleep(0.5) # half a second
